Application filed. 'June:26, 1917, Serial No. 17 ,0l Renewed February .19, 1920."Seria1 No. 359,853.

To all whom it may concern Be' it known that I, ALBERT A. XVRAY, a citizen of the United States, residing at Fredonia, in the county of Vilson and State of Kansas, have invented certain new and useful Improvements in Computing-Table Devices, of which the following is a specification.

This invention relates to an improved cabinet for use in connection with a 001m puting table and the principal object of the invention is to provide a cabinet in which a ribbon may be mounted with its end portions connected with rollers extending transversely through the cabinet and rotatably mounted between the body of the cabinet and theremovable forward section thereof, the forwardsection being releasably con nected with the bodybeneath the overhangmg top ofthe cabinet and having its front wall provided with cutouts through which the ribbon willbe viewed-when the device is in use.

Another object of the invention is to so construct this cabinet that the removable forward section thereof may be easily and quickly removed when it is. desired to remove the rollers carrying the table.

Another object of the invention is to provide a cabinet which will be simple in construction but strong and durable and easy to operate.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing the improved cabinet in front elevation,

Fig. 2 is a vertical sectional View through the improved cabinet,

Fig. 3 is a fragmentary sectional view through the cabinet taken along the line 3-3 of Fig. 2.

Fig. 1 is a detail sectional view of one of the rollers and its support.

This cabinet is provided with a main section or body having side walls and a rear wall 11, the side walls being connected with the rear wall in any suitable manner and theside and rear walls carrying a top or cover 12 which cover overhangs the forward edges of the side walls as shown in Fig. 2. The forward section or auxiliary section of this cabinet is provided with side strips or walls 13 fitting upon opposite sides of the cross strip 14 secured to the underface of the top 12 and engaging the forward edge faces of the side walls 10 of the main section or body. Upper and lower spacing strips 15 and '16 and intermediate strips 17, 18 and'19 are secured tothese side strips 13 and taken together provide a front wall for the auxiliary section having cutouts at points intermediate the height of the forward wall for a purpose to be hereinafter brought out.

In order to releasably hold this forward section in engagement with the ma n section, there has been provided hooks 20 and 21 pivotally connected with the side strips 13 and engaging pins 22 carried by the side walls of the main section. These pins are provided with heads as shown in Fig. 2 and it will be readily seen that when the auxiliary section is put in place and the hooks are moved to engage the pins, the auxiliary section will be securely held in place. The cross strip 1 prevents any tendency to transverse movement and therefore undue strain will not be placed upon the hooks.

The ribbon 23 upon which the table will be printed has its end portion pasted or otherwise connected with the rollers 2- tand 25, the rollers having their end portions provided with stub shafts 26 in order to rotatably mount the rollers. A third roller 27 is positioned beneath the roller and has its end portions reduced to provide stub shafts 28 which stub shafts are similar to the stub shafts 26. In order to rotatably and releasably mount the rollers, the contacting edge portions of the side walls 13 and 10 have been provided with cutouts 29 and 30 which cutouts register when the walls are brought together thus providing bearings in which the stub shafts of the rollers 24, 25 and 27 will be rotatably mounted. These stub shafts extend beyond the sides of the cabinet and are provided with enlarged heads 31 so that the rollers can be easily rotated. A sheet 32 will be pasted or otherwise secured about the roller 27 and will have a table printed upon it, the table being viewed through the slot 33 formed between the strips 16 and 19. The strips 17 and 18 have been positioned close together thus providing a slot 3 1 through which a selected line of figures may be seen. It is of course obvious that if desired to make use of more than one line of figures, the ribbon may be moved so that these figures will show between the strips 15 and 17 or between the strips 18 and 19. It is of course understood that any number of tables may be printed upon the ribbon 23 and that when in use, the ribbon will be wound upon one of the rollers 24 or 25 until the proper table is brought into position for use. If it is desired to remove the rollers to substitute rollers containing a ribbon having different tables shown thereon from that already in use or if the ribbon should become torn and it is desired to replace the ribbon, it is simply necessary to release the hooks 20 and 21 and the auxiliary or forward section can then be removed and the rollers taken out and then replaced after the necessary change has been made.

I have thus proi'ided a cabinet so constructed that easy access may be had to the interior of the cabinet and have further provided a cabinet in which the ribbon may be easily wound upon a desired roller by rotating the rollers. I have further provided acabinet which is so constructed that the auxiliary section will be securely but rcleasably held in place and have also provided a cabinet in which tables which are constantly in use may be protected from wear and from being lost or misplaced and at all times kept where ready access to the tables may be had.

What is claimed is 1. A cabinet of the character described comprising a main section having side walls, a top overhanging the side walls, a cross strip carried by the top and positioned between and in front of the side walls, an auxiliary section having a forward wall having sight openings formed therein and having side walls engaging the ends of the cross strips and the forward edge faces of the side walls of the main section, the contacting edge portions of the side walls being provided with cutouts forming pockets, rollers extending transversely through the cabinet and having stub shafts rotatably mounted in the pockets, and a ribbon connected with said rollers whereby the ribbon may be wound upon the rollers and moved for display purposes across the sight-opening in the front wall of the auxiliary section.

2. A cabinet comprising a main section having side walls, a cover carried by the side walls and extending forwardly of the side walls, a cross strip carried by the cover and positioned between and in front of the side walls thereof, an auxiliary section having side strips engaging the side walls of the main section and engaging the ends of the cross strips positioned beneath the cover to hold the auxiliary section against transverse movement, the contacting edge portions of the rollers extending transversely through the cabinet and rotatably mounted therein, and fasteners releasably connectin the side strips of the auxiliary section wit 1 the side walls of the main section.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT A. WRAY.
